Medication for Enlarged Prostate

An enlarged prostate is a common occurrence in most men as they age. Some symptoms include the inability to fully empty the bladder, weak urinary stream and a strong or sudden urge to urinate. There are treatment medications available.

  1. Definition

    • The prostate gland produces the fluid that carries sperm during ejaculation. The enlargement of the prostate is known as benign prostatic hypertrophy, or BPH. It is not cancerous and does not increase the risk of prostate cancer.

    Alpha-1 Blockers

    • The alpha-1 blockers used to treat BPH include Uroxatral (alfuzosin), Cardura (doxazosin), Flomax (tamsulosin) and Hytrin (terazosin). These drugs work by relaxing the muscle of the prostate, alleviating symptoms. They begin working almost immediately and are effective. Side effects vary and may include lightheadedness, fatigue, stomach upset or nasal congestion.

    5-Alpha Reductase Inhibitors

    • Another type of medication is 5-alpha reductase inhibitors, which work by reducing the prostate. Drugs in this category include Proscar (finasteride) and Avodart (dutasteride). Unlike the alpha-1 blockers, symptoms may not subside for three to six months. Side effects may include erectile dysfunction, reduced semen and lowered libido.

    Other Medications

    • Occasionally, BPH is accompanied by an inflammation of the prostate. Some men who have taken antibiotics to treat the inflammation have also reported a reduction in other BPH-related symptoms.

    Herbal Treatments

    • Saw palmetto is an over-the-counter herbal remedy that can be used as an alternative medication. Some studies have indicated that saw palmetto is effective in the reduction of BPH symptoms, while others have shown no difference between it and a placebo.
